>>> import copy
>>> dir(copy)
['Error', '_EmptyClass', '__builtins__', '__doc__', '__file__', '__name__',
'_copy_atomic', '_copy_dict', '_copy_dispatch', '_copy_inst', '_copy_list',
'_copy_tuple', '_deepcopy_atomic', '_deepcopy_dict', '_deepcopy_dispatch',
'_deepcopy_inst', '_deepcopy_list', '_deepcopy_tuple', '_keep_alive', '_test',
'copy', 'deepcopy', 'error']

what you want is copy.deepcopy().
